We show that an instanton with high charge can provoke the creation of extra curvature on space holds it. Geometrically, this corresponds to a new surgery operation, which we name grafting. Curvature around sphere increases by grafting when decays.

We demonstrate grafting of nitroxide radicals on the surface of nanodiamonds (NDs). The surface of NDs is functionalized by azide groups. Nitroxide radicals are covalently bonded using Cu(I)-catalyzed azide/alkyne-click chemistry approach. The reaction is confirmed by infrared spectroscopy. The grafting of nitroxides is also verified by studying the rotational correlational time using electron ...

Masquelet technique, which is the use of a temporary cement spacer followed by staged bone grafting, is a recent treatment strategy to manage a posttraumatic bone defect. This paper describes a series of 9 patients treated with this technique of staged bone grafting following placement of an antibiotic spacer to successfully manage osseous long bone defects. The injured limbs were stabilized an...

OBJECTIVES To validate ascending aorta-lower abdominal aorta bypass grafting treatment for patients with descending aortic coarctation and an aortic valve disease. METHODS The three patients in whom a descending atypical aortic coarctation was associated with an aortic valve disease were treated with one stage surgical treatment with aortic bypass grafting through the diaphragm and aortic val...

In a series of Polynesian pearls collected after short cultivation periods, early post-grafting mineral deposits were characterized by high resolution synchrotron-based X-ray fluorescence with unprecedented accuracy. Morphological patterns and elemental composition are correlated through simultaneous imaging processes. Evidence that aragonite calcite occur in neighboring units during the earlie...

In the commercial production of roses, introducing a method to reduce the time of propagation with maximum success is crucial. This study was conducted to investigate the effect of different concentrations (0, 1500, 3000, 4500 mg/L) of Indole-3-butyric acid (IBA) on propagation of three cultivars of Rosa hybrid L. ('Dolce Vita', 'Samurai' and 'Utopia') by stenting (simultaneous cutting and graf...

Abstract Background Diffuse coronary artery spasm after bypass grafting may cause disastrous circulatory collapse and death if not detected managed promptly. Case presentation Four out of 387 patients who underwent uneventful off-pump between January 2019 December 2021 at our centre developed unexplained arrhythmias hypotension within 2 to 6 h the postoperative period. Coronary angiogram showed...

Abstract The objective of this work was to evaluate air layering, cutting, and grafting, with different indolebutyric acid (IBA) rates, for the vegetative propagation Eugenia involucrata. Air layering carried out two consecutive years five IBA rates. Cutting tested woody herbaceous cuttings, using four in three seasons. grafting methods – cleft graft splice were For trials experimental designs ...

heparin- induced thrombocytopenia (hit) is an antibody mediated adverse effect of heparin therapy which is classified into two subtypes, hit i which is non-immune, spontaneously reversible thrombocytopenia and; hit ii which is an autoimmune-mediated adverse effect of heparin therapy. in this case report, we described a 65-year old male patient with hit ii after coronary artery bypass grafting. ...

LetX be a closed oriented hyperbolic surface and γ a simple closed geodesic, which is short on X. We show that the iterated grafting grtγgrsγX is close to the grafting ray gr(s+T )γX in the Teichmüller metric, where the bounds depend on the length of γ only. Using this result, we show that the holonomy lifts gr2πγgrtγX of a grafting ray all lie in a r-tube around the ray grtγX and the rays grtγ...
